Beware of competition in healthcare

Competition among Health Care Providers – Investigating Policy Options in the European Union

Let's imagine an official in European Commission. They are in favour of more competition in health care and asks an expert committee to assess the issue. This is the concrete answer in selected statements from the report:
First, and foremost, introducing or increasing competition in the provision of health care services is a delicate policy exercise. The conditions for success and risks for failure need to be carefully assessed. In the right context, introducing competition may help to meet some health system objectives, although it is unlikely to contribute simultaneously and positively to all.

Neither economic theory nor empirical evidence support the conclusion that competition should be promoted in all health services

Neither competition nor strict reliance on government regulation will solve all health system problems. Attempts to avoid or correct market failure can result in government failure and vice versa.

Provider competition can contribute to improving value in health service delivery, but details about where, when and how to introduce competition are critical. Competition in health care provision will not solve all health system problems and may have adverse effects.

Competition is unlikely to achieve improvement in all aspect of health system performance at the same time. It will not solve all the trade-offs policy makers face between different, sometimes conflicting, health system objectives.

Competition can at the same time increase the number of services provided and billed, creating uncertainty in relation to overall health care costs. That is, the introduction of competition may well result in increased costs and add to fiscal pressures. Increased costs may, or may not, be justified by additional health benefits to the population (or some parts of the population).

As competition is an instrument, sound policy evaluation studies are needed to assess and judge its effects. Such empirical studies are currently rare and even absent in some countries.

The introduction of competition has uncertain effects on equity of access to health care, as it is conditional on the effects above and on the heterogeneity of patients. Empirical work has found that the introduction of competition among hospitals, in the UK, produced little or no result in equity terms. This limited evidence does not allow for general presumptions about the effects of competition on equity of access to health care.
Now it is crystal clear. The official has had a precise answer that it is exactly the opposite they were expecting. I've said the same in this blog several times. Take care.

Implications of real world data

Breaking New Ground with RWE

Some decades ago evidence based medicine was the key issue in understanding effectiveness in health care and drugs. Right now the new term is Real World Evidence. You'll not find it in the wikipedia, instead I would suggest you look at this IMS report:
RWE is drawn from robust anonymous patient-level data using sound scientific and commercial analytics. It is not about amassing "Big Data" so much as performing targeted analyses on ever expanding healthcare datasets.
While RWE is known to complement data from Randomized Clinical Trials (RCTs), its real potential is in moving decisions away from perceptions and broad extrapolations to the actual facts about patient journeys and outcomes. With innovations in data and technology, RWE is replacing other information sources such as non-behavioral primary market research (PMR), standard market reports, consumption/market data purchases, observational studies, and even selected spending on RCTs.
Its impact could be large if drug prescription decisions and pricing takes into account the outcomes from the "patient journey" as they say. This is a new paradigm with uncertain spillovers. The true evidence based medicine with the power of big data. We must be aware of it and follow it closely.

PS. How to introduce innovative medicines?. Have a look at this workshop.

Organising genetic testing

Finally the government has decided to organise genetic counseling and testing. A recent instruction determines who does what. As you may remember I've said several times that government was on permanent holiday on this issue.
In this new instruction, at least two issues are forgotten: the tests that are covered, and the proliferation of sequencing instruments outside the lab. These are not minor issues.
Somebody should decide asap wether a test it is worth to be prescribed. Right now, there are no explicit constraints under the current instruction. And DNA sequencing instruments may be found in many departments under the consideration of research. If there is no clear split between research and care, I can imagine a close future with many messy labs within any hospital. Concentration of knowledge and specialisation provides wider guarantees for quality. Unless there is any mentorship program by clinical laboratories, things will go down the wrong path. Today I'm more worried than yesterday, unless these two issues are fixed.

Changing health behavior (once again)

World Development Report 2015: Mind, Society, and Behavior

Understanding human behavior is one of the main scientific endevours of our current times. As I have explained before, psychology, economics and neurosciences are making great progress in the last decades. Now the annual report by the World Bank puts all this stuff in one publication:
Three principles stand out as providing the direction for new approaches to  understanding behavior and designing and implementing development policy. First, people make most judgments and most choices automatically, not deliberatively: we call this “thinking automatically.” Second, how people act and think often depends on what others around them do and think: we call this “thinking socially.” Third, individuals in a given society share a common perspective on making sense of the world around them and understanding themselves: we call this “thinking with mental models".
In chapter 8 you'll find the application to health issues. A clear warning:
Telling people that there is a way to improve their health is rarely sufficient to change behavior. In general, successful health promotion campaigns engage people emotionally and activate or change social norms as much as they provide information. The message disseminated should be that others will support you or even applaud you if you do it, not just that something is good for you. Successful campaigns address many or most of the following: information, performance, problem solving, social support, materials, and media . A campaign should tell people that a behavior will improve their health (information), demonstrate and model the behavior (performance), reduce barriers to its adoption (problem solving), create a system for supporting people who choose to adopt it (social support), provide the materials necessary to begin adoption (materials), and provide a background of support through in-person, print, radio, television, and other approaches (media).
As you may imagine, this is much more difficult than simply giving information. This is precisely the greatest challenge.

Health across borders

Let's think of two countries artificially separated by political borders. Both have the same income per capita (~27,700 €) and belong to the EU. The first spends 11.1 % of GDP on health (5,513€ per capita, 77.7% public funding), while the second only 8% (3,898€ per capita, 65.8% públic funding).
Both countries have roughly the same life expectancy at birth. Healthy life expectancy at 65 is better in the country that spends less. The number of visits and hospitalizations is also less. Physicians are also paid less, 18% less in general practitioners income, up to 40% in specialists income.
There is only one border between them, an artificial border created by a treaty to end a war that lasted 30 years. This is the case of part of France and Catalonia. While the first can decide over the size of resources devoted to health, the second has no role on it, by now.

PS. Today at COMB, French health reform. I'll be there. #sanitatfrança

The value of vaccination

Valuing vaccination

A PNAS article sets a broader perspective on valuing vaccines. It is of interest in light of current difteria case. My position is clear, no doubt about mandatory vaccination if its cost-effectiveness is proven.
Suggestions from the article:
Three general recommendations flow from our arguments and related synthesis of existing evidence on broad benefits of vaccination. First, many economic evaluation studies of vaccinations should be redone to capture the full benefits generated by the vaccination in question. Second, the evidence to date on the full value of vaccination has been focused on measuring the total social benefits generated. It would also be useful to explore the distribution of vaccination’s benefits among different possible beneficiaries. Third, the primary empirical evidence on broad vaccination benefits will need to be considerably expanded and improved


Framework of vaccination benefits
PerspectiveBenefit categoriesDefinition
BroadNarrowHealth care cost savingsSavings of medical expenditures because vaccination prevents illness episodes
Care-related productivity gainsSavings of patient’s and caretaker’s productive time because vaccination avoids the need for care and convalescence
Outcome-related productivity gainsIncreased productivity because vaccination improves physical or mental health
Behavior-related productivity gainsVaccination improves health and survival, and may thereby change individual behavior, for example by lowering fertility or increasing investment in education
Community health externalitiesImproved outcomes in unvaccinated community members, e.g., through herd effects or reduction in the rate at which resistance to antibiotics develops
Community economic externalitiesHigher vaccination rates can affect macroeconomic performance and social and political stability
Risk reduction gainsGains in welfare because uncertainty in future outcomes is reduced
Health gainsUtilitarian value of reductions in morbidity and mortality above and beyond their instrumental value for productivity and earnings

Reviewing the residency system

Let Me Heal. The Opportunity to Preserve Excellence in American Medicine

We usually emphasize the level of resources when we assess the results of our health system. Institutions matter, we already know that. And if there is one key success factor in our healthcare is the physician's residency program. Training of the physicians under "real" conditions has allowed substantial improvements in health outcomes and the progress of medicine that are difficult to measure specifically. In a new book, Ludmerer provides an excellent review of what it represents to US healthcare:
At the core of the residency system are fundamental educational principles: the assumption of responsibility by residents in patient management, and the importance of providing residents sufficient time to reflect and pursue subjects in depth. Also at the core are the moral principles of residency training: thoroughness, attention to detail, and learning that the needs of patients should come first
And considers that
The current turmoil in health care delivery offers the profession and public the opportunity to redesign medical education and practice in ways that more fully serve the needs of patients, present and future.  The opportunity is there to envision medical education and practice as they should be, not as they are,  and to work toward achieving that end. Such opportunities are to be treasured, not feared. The country will always need good doctors, and the medical profession has little to fear in the changes ahead as long as it remembers that it exists to serve, that the needs of patients come before its own, and that it always must be thinking of improving the future as well as caring for the present.
This call for a redesign of medical education and practice is a real need in our environment. The confusion between the role of  "student" and "employee" is increasing and there is no effort to clarify it.The number of physicians in the program is determined without any clear estimation of demand and rules. A total mess. That's why I consider that we should rethink it from its foundations.
